Registering and operating a UTV on public roads is a complex legal process. Many side-by-side owners make simple, avoidable mistakes that result in failed DMV inspections, rejected mail-in packets, or expensive tickets from law enforcement officers. This guide covers the top ten most common mistakes and how to avoid them.
1. Assuming Out-of-State Plates Grant Absolute Immunity
The single biggest mistake is believing that having a South Dakota or Montana license plate makes your UTV legal in your home state. While plate reciprocity is generally honored for visitors, local police officers can ticket you if you are a resident of the state and have your vehicle registered out-of-state to avoid local registration taxes or safety regulations.
2. Using Non-DOT Approved Tires
Many riders buy a turn signal kit but leave their stock off-road tires on the UTV. If your state requires a vehicle inspection (like Utah), you will fail immediately if your tires do not have the "DOT" stamp on the sidewall.
3. Lacking a License Plate Light
A very common oversight when installing DIY kits is omitting the license plate light. Most state laws mandate that the rear license plate must be illuminated by a white light that is active whenever the tail lights are on. Without it, you are highly likely to be pulled over at night.
4. Riding on Interstate Highways
Even in states like Arizona and Utah where UTVs are treated exactly like cars, they are strictly prohibited from operating on controlled-access interstate highways. Always plan your routes using secondary county and state routes.
